“…The results of holmium laser lithotripsy for ureteral calculi have been uniformly excellent [11,[14][15][16][17][18][19]. Successful fragmentation of calculi is achieved in more than 85% cases.…”

“…The mean (range) duration of the procedure was 72 (45-125) min, of fluoroscopy was 17 (13-58) s and of hospital stay was 3.8 (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) days. Of the 28 ureteroscopies, 17 (61%) required mechanical dilatation of the ureteric orifice before negotiating the 8 F ureteroscope into the intramural ureter.…”

“…Furthermore, judicious irrigation is warranted during lasertripsy to dissipate heat and facilitate visualization. Without irrigation the scattering of stone fragments creates a 'snowstorm' appearance, which obscures vision and makes it difficult to monitor the fibre tip [13]. Our technique of manually controlled irrigation using a 20-mL syringe attached to the outlet port of the ureteroscope allows controlled flushing for clear visibility and dissipation of the heat, with minimal risk of displacing the stone.…”

laser energy delivered at 0.6-1.4 J and 6-10 Hz. All patients were evaluated after 3 months with intravenous urography to confirm stone clearance and to exclude ureteric stricture formation. RESULTSThe overall stone-free rate was 92% (24 children) after 28 ureteroscopic procedures. Stones were completely cleared in 83%, 80% and 100% of the procedures in the upper, mid-and lower ureters, respectively. In two children the procedure failed; they were salvaged by ureterolithotomy in one and extracorporeal shockwave lithotripsy in the other. During the procedures, a ureteric perforation was caused by several factors, including a technically difficult procedure and higher laser energy. At the mean (range) follow-up of 18 (3-39) months, low grade vesico-ureteric reflux was detected in two children, and there were no ureteric strictures in any. CONCLUSIONHolmium:YAG laser lithotripsy is an efficient and safe treatment for ureteric calculi in children.

“…This risk can be minimized by stent placement at the time of stone manipulation. Advances in ureteroscopic technology with the introduction of small caliber semi-rigid and flexible ureteroscopes combined with the introduction of the holmium YAG laser have improved stone free rates following ureteroscopy while decreasing the risk of complications (24,25).…”

�BSTR�CTPurpose: To assess the efficacy of extracorporeal shockwave lithotripsy (ESWL) for ureteral calculi during acute renal colic. Materials and Methods: From January 2002 to March 2007, 108 patients were treated by ESWL for obstructing ureteral stones causing acute renal colic. ESWL was performed within 24 hours of the onset of renal colic. Results: The mean age of the patients was 39.5 years (11-72 years). Male/female ratio was 85/23. Mean stone size was 8.45 mm (4-20 mm). They were located in the pelvic (n = 53), iliac (n = 28) or lumbar (n = 27) region. Fragmentation after a single session was complete in 56 patients (52%), incomplete in 28 (26%), and absent in 24 (22%). Patients presenting incomplete fragmentation underwent a second (n = 28) or even a third session (n = 11). Of the 24 patients in whom ESWL had no impact on the stone, 21 underwent ureteroscopy, and in one case open ureterolithotomy for a patient with a hard 17 mm stone, while spontaneous passage occurred in two patients with small stones. Conclusion: Emergency ESWL for obstructing ureteral stones has a satisfactory success rate and very low morbidity. The stone-free rate of retreating ureteral calculi with ESWL decreases significantly after failed initial treatment. Stone size may be the main predictive factor for retreatment. We suggest that no more than 3 treatments should be given for a particular stone due to minimal improvement in the subsequent cumulative treatment success rate.
